2 Claims.

This invention relates to improvements in window constructions.

In the type of window construction which comprises a frame and sash members formed from extruded metal, such as aluminum, it isdifficult to obtain a satisfactory weatherproof construction which will prevent leakage between the side frame member and the ends of the sash meeting rail at the point where the meeting rails are positioned relative to the side frame member when the window is in closed condition. In ordinary constructions the end of the sash meeting rail is spaced from the side frame member to allow suflicient clearance for the free vertical movement of the sash. This space between the end of the meeting rail and the side frame member permits passage of water and dirt upwardly from the outside of the window and into the interior.

It is an object of the invention to provide a window construction wherein a weather block is permanently secured to the side frame member at the point where the ends of the sash meeting rails are positioned when the window is in closed condition, which block is so constructed that it does not interfere with the movement of the sash but at the same time fills the space between the ends of the meeting rails and the frame and prevents the passage of water and dirt therethrough.

These and other objects will be apparent from a description of the preferred form of the invention which is shown, by way of illustration, in the accompanying drawings, wherein:

Fig. 1 is a perspective View of a portion of a window construction embodying the principles of the invention, the bottom movable sash being omitted;

Fig. 2 is a section on the line 2-2 of Fig. 1, with the bottom movable sash in closed position;

Fig. 3 is a section on the line 33 of Fig. 2;

Fig. 4 is a section on the line 44 of Fig. 1;

Fig. 5 is a perspective view of the weather block member; and

Fig. 6 is a perspective view of the retaining clip for the weather block member.

The invention is illustrated in the drawings in connection with a window construction of the type having an upper fixed sash and a lower movable sash wherein one meeting rail is rigidly joined at its ends to the side frame members to form the bottom of the fixed sash while the other meeting rail forms the top rail of the movable sash which is slidable vertically in side guide channels provided in the side frame members. Only one side of the window is illustrated. It will be understood that the construction will ordinarily be incorporated in both sides of the window. The lower movable sash is not shown in Fig.

1. It is shown in the closed position in Figs. 2 and 3.

In the construction shown, the side frame or jamb member In is formed from an extruded metal section to provide an inner guide channel forming portion I I for reception of a sliding sash and an outer portion l2, the upper half of which constitutes the side member of a fixed sash. The horizontal meeting rail 13 forms the bottom member of the fixed sash and is rigidly joined at its end to the side frame member Ill. The portion I2 of the side frame In andthe meeting rail l3 are constructed to provide a glazing channel M for reception of one or more panes of glass (not shown). Th meeting rail ['3 is provided with a groove I5 for receiving a glazing strip (not shown) to secure the panes of glass in the channel Id. The meeting rail l3 includes an inner face plate l6 and a channel formation ll for cooperating with portions of the meeting rail on the movable sash.

The inner portion ll of the frame member It] includes an inside face plate is and an oppositely disposed flange portion is connected adjacent their outer edges by a web portion 20 forming a side guide channel 2| in which the vertical side member 22 of the movable sash 23 is received. The inner portion ll of the side'frame member ID is connected to the outer fixed sash forming portion [2 by an intermediate web member 24 which extends to the inner face plate 25 of the portion l2 and is integrally joined along one side thereto in angular relation, forming a vertical recess or corner.

The movable sash 23 includes the vertical side member 22 and a top or meeting rail 26 which are joined at their ends in abutting relation. The meeting rail 26 is provided with an outer portion 21 forming a downwardly opening channel which is adapted to receive the upper portion of the faceplate IE on the meeting rail I3 when the sash is in closed condition. Weather strip carrying members 28 are secured in the channel portion 21. The meeting rail 26 is secured to the side member 22 in any conventional manner to provide a rigid frame. The meeting rail 26 and the side member 22 are provided on their inner sides with a glazing channel 29 for receiving one or more panes of glass (not shown) and a groove 30 for receiving a glazing strip (not shown) to secure the glass panes in position. The end of the meeting rail 26 is cut away at 3| to provide clearance for free vertical movement of the sash 3 and the side member 22 is provided with a weather-strip member 32.

The fixed meeting rail I3 is cut at its end 33 so that the inner portion thereof including the face plate It is spaced from the web portion 24 of the vertical side frame member ID when the members are in assembled relation.

A weather-strip block 34 of felt, or similar material, and of the shape illustrated in Fig. is provided which is adapted to be positioned between the end of the meeting rails i3, 25 and the vertical face of the side frame member Ill. The inner face 35 of the block 34 is beveled at the ends 36 and 31 while the outer face 38 is provided with a flanged portion 39 extending along the inside edge. The block 34 is of sufficient transverse cross section to substantially fill the space between the end 33 of the meeting rail l3 and the adjacent portions 24 and 25 of the side frame member ID and is positioned with the flanged edge portion 39 extending outwardly along the inner face of the portion l9 of the frame member II].

A holding clip member 40 is provided for securing the block 34 in position on the web portion 24. The member 40 is preferably made Of a relatively fiat hard metal, such as stainless steelplate, and comprises an intermediate portion 4| terminating in beveled end portions 42 and 43. One end 42 is provided with an angular lug or extension 44 of reduced width. The other end 43 is provided with a fiat lip or extension 45 which is in parallel offset relation to the intermediate portion 4| and which is provided with an aperture 45. The web portion 24 of the frame I0 is provided with a transverse slot 41 above the block 34 which is adapted to receive the angular lug member 44 of the holding clip 40 in interengaging relation. A tapped hole 48 is provided in the web portion 24 at a spaced distance below the slot 41 for reception of a threaded screw 49 by means of which the holding clip 40 is secured in position. The portion 4| of the clip 40 is in abutting relation with the end 33 of the fixed meeting rail l3. The weather block 34 completely fills the space in the corner between the end 33 of the fixed meeting rail l3 and the portions 24 and 25 of the side frame Ill and extends laterally inwardly a suincient distance to fill the space between the end 3| of the movable meeting rail and the portion 24 of the side frame member I!) when the sash 23 is in closed position. The flanged portion 39 of the block 34 extends into the side guide channel 2| and cooperates with the weather-strip member 32 to fill up the small space between the sash side member 22 and the portion [9 of the side frame member III.

The novel construction is illustrated in the drawings as incorporated in a window having a frame provided with a top fixed sash portion and having a lower movable sash mounted in sliding relation therein. The construction is also applicable to a double-hung sash type window wherein the meeting rails are both movable relative to the side frame or jamb member. The weather-strip block is positioned in the doublehung sash type window so that it fills the space between the ends of the meeting rails and the adjacent side frame member when the sash are in closed condition.

While specific details of construction and materials have been referred to in describing the illustrated form of the invention, it will be understood that other details of construction and other materials may be resorted to within the spirit of the invention.
